' Application filed August 3, 1904. Serial No. 219,302. (No model.)

T0 at whom it may concern:

Be it known that I, RIoHARD Y. YEOMANS, a citizen of the United Statesof America, residing at Beaverfalls, in the county of Beaver and Stateof Pennsylvania, have invented certain new and useful Improvements inRotary- Brush Machines, of which the following is a specification,reference being had therein to theaccompanying drawings.

This invention relates to certain new and useful improvements inrotary-brush machines; and the invention has for its object theprovision of novel means whereby two brushes maybe revolvedindependently of one another and in opposite directions.

Another object of this invention is to provide a machine of the abovetype wherein novel means is employed for automatically moving thebrushes at predetermined times, also means whereby said brushes may beadjusted upon their respective shafts.

To this end my invention contemplates a machine which is particularlyadapted as a cleansing-machine for removing sand, dirt, and the likefrom articles that are placed within the machine. The machine asconstructed in accordance with my invention is adapted to be used in themanufacture of chinaware and the like, and to facilitate the clearunderstanding of my invention I will describe the same throughout asbeingused for removing sand from chinaware.

In the manufacture of chinaware the plates and saucers and the likeafter they have been subjected to a high degree of heat are cooled, andwhen they have reached a cool state they have sand and the like adheringto their surfaces, and to remove this sand I have devised the presentinvention, whereby each plate or saucer may be placed within my improvedmachine and the sand cleansed therefrom.

With the above and other objects in view, Which will more readily appearas the nature of the invention is better understood, the same consistsin the novel construction, combination, and arrangement of parts, whichwill be more fully described and then specifically pointed out in theappended claims.

Reference will now be had to the drawings accompanying this application,wherein similar reference characters designate corresponding parts.

To put my invention into practice, I employ a suitable table whichconsists of a rectangular framework, the framework comprising the legs 11 and 2 2, which are braced by the longitudinal beams 3 and i and thetransverse end beams 5 5. The table is formed with a top 6, which is cutaway, as indicated at 7, 8, and 9, to form areaways in which a portionof the mechanism employed in connection with my improved machine ismounted, these areaways forming transverse beams 10 and 11, and upon therear edge of the table and upon the beams 10 and 11 and the end frames12 and I I I secure a plate 15, this plate being cut away, as indicatedat 16, the object of which will be hereinafter more fully described.

The main power-shaft 17 of the machine is journaled in suitable bearings18 18, which are mounted upon the transverse beams 5 5, respectively.The power-shaft 17 has mounted thereon, preferably near one end, astepped pulley-wheel 19, and to this pulley-Wheel 19 is conveyed thepower which operates the ma chine. The reference-numeral 20 designatesanother shaft which is journaled in bearings 21 21, mounted upon thetransverse beams 5 5, respectively, and this shaft has mounted thereontwo pulleys 22 22. A counter-shaft 23 is journaleol in an enlargedportion 24, that is formed integral with one of the legs 5 of the table,and in a depending arm 25, which is carried by the top of the table.Upon said shaft are mounted pulleys 26 and 27, and over the pulley 26passes a belt 28, which passes around the pulley 22 of the shaft 20.Apulley 29 is mounted upon the power-shaft 17, and around this pulleyand the pulley 27 of the counter-shaft 23 passes a belt 30, whereby arevoluble motion will be imparted from thepower-shaft 17 through themedium of the counter-shaft to the shaft 20.

The main operating-shafts A and B, of which there are two, are journaledin bearings 31 31 and 32 32, mounted upon the transverse beams and 11and the end frames 12 of the table. The inner ends of the mainoperating-shafts A and B terminate in the areaway formed by thetransverse beams 10 and 11, and upon the inner ends of said shafts aremounted the rotary brushes 33 33, said brushes being secured to saidshafts by set-screws 34 34, which pass through the collars 35 35,carried by the brush-heads 36 36. Upon each shaft A and B is mounted apulley-wheel 37 and 38, and over the pulley-wheel 37 of the shaft A andthe pulley-wheel 22 of the shaft passes a cross-belt 39, whereby areverse motion. to that of the shaft 20 is imparted to the mainoperating-shaft A. Over the pulley 38 and the pulley 19 passes a belt40, whereby a similar revoluble motion is imparted from the power-shaft17 to the main operating-shaft B. Upon the outer end of I each of themain operating-shafts A and B is mounted a collar 41 41, and connectedto said collars are the transverse levers 42 and 43. These levers areeach pivoted, as indicated at 44, to an outwardly-extending arm 45,carried by the table, and the rear ends of said levers are formed withenlarged portions 46 46.

Carried by the rear frame 47 of the machine is a depending arm 48, towhich is pivotally connected, as indicated at 49, a T- shaped lever 50.To one end 51 of said lever and to the enlargement 46 of the lever 42 isattached a rod 52, and to the other end of the lever 50 and theenlargement 44 of the lever 43 is connected a rod 53. The objectof theserods and their connections will be hereinafter more fully described.

Mounted upon the longitudinal beam 3 of the frame is a bracket 54, towhich is pivoted, as indicated at 55, a rod 56, which extends at anangle transversely of the machine and has its bent-up end 57 connectedto the T-shaped lever 50. Upon the power-shaft 17 is mounted a cam-wheel58, upon which rests the rod 56, and the cam-wheel is adapted when theshaft revolves to impart a vertical reciprocatory movement to the rod.

To support an article or object between the rotary brushes 33 33, 1secure an' angular bracket to the plate 15, the vertical portion 59 ofthe bracket being provided with a rearwardly-extending lug 60, which issecured to the plate 15, and this vertical portion of the bracket isadapted to lie within the cut-away portion 16 of said plate. Thehorizontal portion 61 of the bracket lies beneath the rotary brushes 3333, and upon this horizontal portion is adapted to be supported thearticle or object which is to be cleansed by the brushes, 5 and in thedrawings accompanying this application I have shown a plate 62 asresting upon the bracket and in position to be cleansed by the rotarymovement of the brushes.

The operation of themachine when it is desired to cleanse the plate isas follows: A revoluble motion is imparted to the power-shaft 17 fromany suitable source of power by placing a belt over the pulley 19. Whenthe power-shaft 17 revolves, a similar movement is imparted to the mainoperating-shaft B by the belt 40, which travels over a portion of thepulley 19 and over a pulley 38, carried by said operating-shaft. Arevoluble motion is imparted to the counter-shaft 23 through the mediumof the belt 30 and the pulleys 29 and 27, and from the counter-shaftthis movement is imparted to the shaft 20 by the belt 28 and the pulleys26 and 22. From the shaft 20 the motion is imparted in a reversedirection to the main operating-shaft A, this being accomplished bycrossing the belt 39, as clearly shown in Fig. 1 of the drawings. Thebrushes revolve in opposite directions and thoroughly cleanse both sidesof the plate of all sand or dirt that is upon the same, and to providemeans whereby the plate may be removed and another plate inserted I haveemployed the following mechanism, reference being had to Figs. 1 and 2of the drawings: It will be seen by the construction of the top of thetable and the areaways that a longitudinal movement in respect to thetable is permitted of the main operating-shafts A and B, the areawaysbeing of sufficient width to permit a longitudinal movement of thepulleys 37 and 38, also of the rotary brushes 33 33. To automaticallyperform this movement of the rotary brushes at predetermined times, thecam-wheel 58 is mounted upon the power-shaft 17, and through the mediumof the pivoted rod 56 an oscillating movement is imparted to theT-shaped lever 50, and as this lever oscillates upon its pivot thelevers 42 and 43 will receive a like movement, owing to the same beingpivoted upon the outwardly-extending arms 45 of the table. As theselevers are connected to the collars 41 41, which are secured to the,main operating-shafts A and B, these shafts will be reciprocatedlongitudinally of the table, the levers being so connected to theT-shaped lever 50 that the main operating-shafts A and B will be movedoutwardly and inwardly, permitting a sufficient space to exist atpredeter mined times between the rotary brushes, whereby a plate may beremoved and another plate inserted between the brushes and placed uponthe bracket carried by the plate 15 of the machine.

It will be observed that the rotary brushes as they become worm may beremoved by loosening said screws 34 34 and removing the same from themain operating-shafts A and B, and these rotary brushes may be adjustedupon the main operating-shafts, as will be permitted by the length ofthe collars 35 35.

IIO

It will also be noted that the counter-shaft 23 oi the machine may beentirely dispensed with and the revoluble motion of the power-shaft 17imparted direct to the shaft 20.

The cam-wheel 58, which I have mounted upon the shaft 17 may be formed apart of the pulley 19 by moving the rod 56 and the T- shaped lever 50,whereby they will be actuated by the cam-wheel 58. In the presentconstruction, as illustrated in the accompanying drawings, the weight ofthe rod 56 is adapted to return the T-shaped lever and the brushes totheir normal position, and if it is desired to insure a more positivereturn movement of said levers and brushes a spiral spring may beconnected to the T-shaped lever 50 and to the frame of the table,whereby the contraction of said spring will return the parts to theirnormal position.

While I have herein described and shown the machine as being adapted forcleansing china, porcelain, and the like substances, 1 wish it to beunderstood that the machine may be readily employed in other arts thanthe one enumerated. The machine may be used for cleansing or polishingarticles placed therein, and while I have herein shown the essentialmechanism that isnecessary to accomplish the desired results I do notcare to limit myself to the specific means shown, but may employ othermechanism than that to accomplish the same results, and other suchchanges may be made without departing from the spirit of the invention.

What I claim, and desire to secure by Letters Patent, is

1. A machine of the character described comprising a table, brushesmounted upon said table, means for revolving said brushes independentlyof one another and in opposite directions, means for automaticallymoving said brushes inwardly and outwardly, and means for supporting anarticle between said brushes.
